To all 'whom it may .Convertir Be it known that l, HUBERT YrrTE, a citizen of the United States of America, residing in the city of Stt Louis and State ot Missouri, have invented certain new and useful Improvements in Car-Seats, of which the following is a Ifull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that character of car seats known as -Xv alk over seats, and which has for its object the production of a simple, efficient and durable means whereby the back of the Seat may be held reclined positions cf different degrees when it is located at either side of the seat.

Figure l is a vertical cross section taken through my car seat, with the members at o ue end of the seat and at the inner side of ,the seat end shown in elevation. Fig. Il is an enlarged view similar to Fig. I, With one ot the rack housings ,omitted to atford a view of the parts back of Said housings. lll is in part an enlarged side elevation of the seat, and part a vertical longitudinal sect-ion.

In the accompanying drawings.: 1 desigf nates the pedestal of my seatand 2 are ,tie

bars or supporting bars that are mounted upon suitable arms at the upper ends of the pedestals.

3 are seat end pieces supported by the tiek bars 2. Each end piece k3 has suitably secured to ita pocket plate 4 that is located at the inner side of the end piece, the pockets in the plates being located at their inner sides. At the top of the pocket in each plate is a pair of stop lugs 5 extending downwardly Within the pocket and spacedv apart from each other, each stop lug being provided with an ontturned lip 6,4(see Fig. II and dotted lines Fig. I.) At the bottoinf of the pocket in each plate are stop lugs 7 that are of service in conjunction with the` stop lugs 5 and their lips, as will hereinafter appear. S designates a rock shaft extending longitudinally of the car seat and having its yends Pocket Plates 4f, (See .Fia-- journaled in the HI.)

-9 designates levers fixed to the lrock shaft S near the pocket plates i at the ends of the Seat and the outer ends of the levers are centrally pivoted to arms 10 that are secured to the ends of the back of the seat, as shown in dette@ lines 1l, (See Fie" l) 12 are links pivoted to the arms 10 at opposite sides et lthe lever 9, and which occupy posit-ions parallel to said lever. The inner ends ,of the links v12 are pivoted to latch bars 13 that are loosely mounted upon the rock shaft 8 are adapted to move independently of rcck shaft when the same is rotated, The latch bars 13 have arms extending laterally from the rock shaft in both directicns to receive the connection of the links 12 at the end of each arm of each latch bar is a inger 14. It should be mentioned that the latch bars 13 are offset from the levers 9 and occupy the pockets in the Decke-f plates 4 15 designates socket pieces of segmental shape that'are located in the pockets in thev pocket plates 4:, and each of which serrated or provided with a plurality of sockets adapted to receive the fingers 14 of the latch bars13. These socket pieces are limited in their inward movements by the stop lugs 5 and in the pockets ,of the pocket plates, and they are normally pressed toward the centers of the pockets in said plates by springs 16 located back et the socket pieces, (see Fig, lli.) The socket pieces and the springs that Qontrol them are partially inclosed by h oiising plates or caps 17 which are suitably secured -to the pocket plates il, all@ which serve to prevent lateral movement ef Said parts- 4121 designates sockets located at the upper edges of each of the pocket plates 4, (see Figs. I and 11,) said sockets being designed to receive coinplenientally shaped lugs 10a carried by the arms 10, said lugs being located aboutmidivay of the length of the arms, or in proximity to the upper point of pivotal ,connection of ,the lever 9.

In the practical use of my invention, the seat back may be moved in the Walk over fashion to one side of the seat proper or the ether., and when in either position the back may be independently adjusted to any desired degree by manipulating said back in the manner about to be described. lVhen it is desired to adjust the inclination ot the seat back, that is necessary to do is to put pressure upon the upper portion of the back in the proper direction and cause the lug 10L to rotate in .its seat, or socket, ta, which movementwill not change the position of the lever 9, but will cause longitudinal movement in opposite directions ot' the links 12, thereby slightly rotating the latch bar 13 on the shaft 8 and cause the fingers 14 of said latch bar to engage the next adjacent sockets I'ormed in the spring actuated socket piece 15, to etl'ect a lock between said seat back and its support. sired to reverse the position of the seat back, the seat back must be in, or brought to, a position of adjustn'ient most nearly approaching the vertical, such as is illustrated in Fig. I of the drawing, whereupon it will be observed that further independent movement oi' the back is prevented by one face or the arm 10 being in contact with the upper face of the pocket plate The back may now be thrown over to the opposite side of the seat, being properly guided in such movement by the lever 9 and the links 12, the latter acting similar to a parallel rule movement, whereby the said back is brought in its new position to the same angular relation to the seat as it was just previous to this walk over movement. Simultaneously with the above movement, the shaft S will be rotated, due to the fixed relation of the .lever 9 thereto which will, through suitable mechanism not described or claimed in this application, move the seat cushion to its proper position relative to the new position attained by the back.
